Wacker Neuson 5000163362 Pump T to Reservoir Hose

The Wacker Neuson is a genuine OEM Pump T to Reservoir Hose designed for RD12 and RD12A series tandem rollers. As a factory-original component, is manufactured to the exact routing dimensions, end fittings, and pressure ratings required by the hydraulic system in these machines. Fitment covers the RD12-90 and RD12A-90 configurations, including solid ROPS and foldable ROPS variants. Choosing a genuine OEM hose ensures a correct drop-in installation with no rework to existing connections.

Key Features

• Factory-Original Hydraulic Hose Construction — Manufactured to the precise pressure rating, inner diameter, and fitting specification required by the RD12 and RD12A hydraulic circuit, ensuring proper flow between the pump T-junction and the hydraulic reservoir.
• Genuine OEM Part — Sourced directly from Wacker Neuson; part number 5000163362 carries the same specification as the hose installed at the factory, with no substitution in materials or end-fitting type.
• Broad RD12 Series Coverage — Compatible with RD12-90 and RD12A-90 tandem rollers across solid ROPS and foldable ROPS configurations, making this the correct replacement across multiple build variants in the RD12 family.
• Maintains Hydraulic System Integrity — A failed or leaking pump-to-reservoir hose causes hydraulic fluid loss, pressure drop, and potential pump damage; replacing with this OEM hose restores full system pressure and prevents further drivetrain wear.
• Direct-Fit Routing and End Connections — Hose length, bend profile, and end fittings match the original installation path, allowing straightforward removal and reinstallation without cutting, splicing, or adapting.

The pump T to reservoir hose is a critical hydraulic return line that carries fluid from the pump tee junction back to the hydraulic reservoir, completing the closed-loop circuit that powers the drive and compaction systems on the tandem roller. If this hose cracks, chafes, or develops a leak at either fitting, hydraulic pressure across the entire system drops, causing sluggish or unresponsive drum drive, erratic vibration output, and the risk of running the pump dry. Replacing a worn hose promptly with the correct OEM part protects the pump and downstream hydraulic components from damage caused by cavitation or fluid starvation.
